Abstract: A floating PV system results from the combination of photovoltaic power plant technology and floating technology. K-Water has installed a 100 kW floating PV system on the water surface on Hapcheon dam reservoir in October 2011 and has been operating it since then. After successfully installing the 100 kW floating PV system, K-Water additionally installed a 500 kW floating PV system on another location nearby in July 2012. The electricity generated by the two floating PV systems installed in Hapcheon dam reservoir is creating profits by being sold to the national power grid. In this article, taking a step further from such fixed-type floating PV, the basic concept of 100 kW tracking-type floating PV and the application plan for the tracking algorithm and the rotation mechanism of structure which is a major design element were explained. As the first case that can maximize the power generation efficiency of PV internationally, it is expected that this study will be utilized as a primary guide for future development of tracking type PV system.
